DRAFT GEAR. i

Appiieanon inea March zo, 1922. serial No. 545,101.

T o all w iom it' may Concern.'

Be it known that l, HERMAN C. Pinnen, citizen ofthe United States, residing at Elue Island, in the county of Cook and State of Illinois, have inventedv a certain new and useful Improvement in Draft Gears, of which the following is a full, clear, concise, and exact-description. v

My invention relates to railway cars and particularly to the underlying structures thereof, and has for its general object the provision. of improved means, for effecting the assembly of draft gears with the balance of the cars.

In accordance with my invention the inner or so-called rear draft lugs with which the limer portions of the draft gears are in abutting relation are not only mounted upon draft arms but, in addition, are reinforced by the adjacent body holsters to avoid or reduce the shearing action upon the rivets which' hold these lugs in place.

My invention is of particular service in connection with freight cars that employ underlying wooden center sills in pairs. .At each end of a car having such sills l provide two angle irons having inner upright sides and lower outwardly extending horizontal sides, each sill having an angle iron individual thereto and received in the align-- lar seat formed by the angle iron. I also provide two horizo-ntal upright draft arms, each angle iron having a draft arm individual thereto and below the same', the lower horizontal side ofeach angle iron being riveted to its draft arm. The inner draft lugs hitherto referred to have their upright sides vriveted to the draft arms and in addition to these upright sides the draft lugs have inwardly extending-top sides which are also riveted to the lower horizontal sides of the contiguous angle' iro-ns.v By means of this construction the draft lugs, in addition to performing their usual function, also serve greatly to strengthen the "assembled angle irons and draft arms and to maintain the fixed relation thereof while undergoing` severe draft strains. This feature of my invention is highly useful and is believed to be novel whether the inner draft lugs are reinforced by the bodybolster or not, and while I have employed this formation in connection with the vinner draft lugs, the in vention. isrnot to be thus limited.

' The top sides of the inner draft lugs are preferably also employed for effecting the ing parts in section and parts in plan of theA under structure of a` car equipped in accordance with the preferred embodiment of the invention; Fig. 2 is a sectional view on line l 22 of Fig. l with the draft gear shown in dotted lines; Fig. 3 is a sectional view on line 3-3 of Fig. 2; Fig. 4 is a perspective view illustrating some of the component parts of the underlying car structure; Fig.

5 is a perspective view of the inner draft lug; and lig. 6 is a view, somewhat dia grammatic, illustrating the draft gears at both ends of the car structure and some of the associate parts, the intermediate portion of the car structure being broken away for lack of space.

Like parts are indicated by similar characters of reference throughout the different figures.

The car body is not illustrated as its presence is understood. As the invention is illustrated, it is provided with two longitudinal wooden center sills l and 2. There are two angle irons having inner upright sides 3 and lower and outwardly extending horizontal sides 4, eachsill having an angle iron individual thereto and received in the angular seat formed by its anglev iron. There are two draft arms or draft sills 5 and 6, each angle iron having a draft arm individual thereto and below the same. Each draft arm is preferably in the form of an upright channel `iron whose horizontal flanges extend outwardly, the lower horizontal side of each angle iron being riveted to the top' flange of its draft arm.

Any suitable form of draft gear is assembled with the draft arm. The gear illustrated includes a coupler 7 and a coupler yoke 8 assembled therewith. The coupler is supported by a key 9 passing therethrough and through elongated slots in the draft arms 5, 6 and also in the front or outer draft lugs 10. The yoke is supported upon a plate 11 bolted to and beneath the bottom flanges of the draft arms. The draft gear illustrated is provided with an outer follower' 12 and an inner follower 13, these followers being illustrated in the form of barrels containing springsor other motion resisting mecha.- nism. a springl 14 being illustrated as entering the barrels. Outward movement of the coupler is opposed by the motion resisting mechanism due to the engagement of the outer follower 12 with the outer draft lugs l 10. Inward movement of the coupler is opposed by the motion resisting mechanism due to the engagement of the inner follower 13 with the rear or inner draft lugs 15, these latter lugs preferably including all of the novel characteristics which are embraced within the formation of d aft lugs in accordance with my invention, although the inventionl is not to be thus restricted.

These inner lugs have upright sides and inwardly extending top sides, each draft arm having a draft lug individual thereto, the upright side of each draft lug being riveted to the upright side of its draft arm.

The top side of each draft lug is riveted to the lowerl horizontal side l of the vcontiguous angle iron. By thus forming and rivetingl the inner draft lugs the union or assembly of thev draft arms with the angle irons and the wooden center sills `is greatly strength Vand whose outer side is in abutting engagement with the lugs 17 and whose inner side is in abutting engagement with the adjacent body bolster 16.

'The distance piece 18 is preferably the base portion of a U-shaped member having upwardly extending sides that are riveted to the upright sides 3 of the aforesaid angle irons. I desirably provide additional angle irons 19 having upright sides against the upright sides of the first aforesaid angle irons and between the same and the upright arms of the distan-ce piece 18. The remaining sides of said additional'angle irons are desirably at the top and extend `inwardly and horizontally. When the inner lugs are thus associated with the body holsters adjacent thereto the shearing strains upon the rivets that hold these lugs in place is effec` tively counteracted. y

Each car that is constructed in accordance withl my invention has7 at 'each `of its ends,

the inner draft lugs 15 and the parts associated and assembled therewith as will be understood by those skilled in thek art and asy somewhat diagrammatically illustrated ink F ig. 6.

lVhile I have herein shown and particular ly described the preferred embodiment of my invention I do not wish to be limited to the precise details of construction `shown as changes may readily be made without 'departing from, the spirit of my invention,v but having thus described my inventionrI claim as new and desire to secure by Letters Patent the followingz- A 1.
